Inventor: SHIMO YOSHIO
IPC: B32B27/36
Filed: 1995-04-14
Abstract: PURPOSE: To obtain an FRP molding having high quality by suppressing the generation of bubble in the part of a complicated shape. CONSTITUTION: The method for manufacturing an FRP molding comprises the steps of setting a preform material 4 previously formed of fiber in a complicated shape at the part of the complicated shape on a surface gel coating layer 2 to form a backing reinforcing layer by spraying up reinforcing fiber and resin at the rear surface side of the layer 2 after a mold 1 is coated with the layer 2, spraying the resin on the part with the material 4, and spraying the fiber and the resin on the part except the part with the material 4 to be molded.

Title: Liquid circulating type battery
Inventor: YOSHIDA YUTAKA
IPC: H01M2/12
Filed: 1983-05-20
Abstract: PURPOSE:To speedily respond even to a sudden pressure change in and out of a battery and wipe out any fear of battery breakdown as well as to prevent an electrolyte from coming into rarefaction due to the run of useless seawater in time of pressure equalization, by installing a valve whose opening area varies according to a pressure differential in and out of the battery. CONSTITUTION:A nylon cloth-make valve body 8 installed in the exhaust port of a liquid circulating type battery having an electrolyte storage part inside the battery and circulating the electrolyte inside the battery cell part is choked in its opening part 10 with an rubber strong 9 and therefore almost nearly closed up. Accordingly, if there is a bit of clearance left in between, no seawater flows inside. When internal pressure is more increased than external pressure by generation of a sub-reactional gas, the valve body 8 opens outward in conformity with a degree of the increased pressure, causing an area of the opening part 10 to be increased to the extent of being proportionate to tension of the rubber string 9, and gas is promptly discharged whereby both internal and external pressures are balanced, thus the valve body 8 is restored to its original state. In addition, when the external pressure exceeds the internal one, the valve body 8 opens inward, leading the seawater inside, and when pressureis balanced, it is restored to the original state as well.

IPC: C12P7/46
Filed: 1979-07-19
Abstract: PURPOSE: To recover a dicarboxylic acid readily an at a low cost, by extracting a dicarboxylic acid with an aromatic hydrocarbon solvent, and then extracting the extracted solvent phase with a dihydric alcohol to transfer the dicarboxylic acid to the alcoholic phase selectively.  
     CONSTITUTION: A fungus body is removed from a fermentation liquid, and an inorganic acid is added to adjust the pH of the liquid to 4.0 or lower. The free dicarboxylic acid is deposited, and the liquid is brought into contact with a solvent consisting of an aromatic hydrocarbon at 60W100°C to extract the dicarboxylic acid in the aromatic hydrocarbon phase preferentially. The solvent phase is then extracted with a dihydric alcohol at 50W100°C to transfer the discarboxylic acid to the alcoholic phase. The dihydric alcohol phase is directly, or after concentration, subjected to the esterification step for forming a polyester. Succinic, azelaic, 1,10- decanedicarboxylic acid, etc. may be cited as the dicarboxylic acid, and a  ≥10C aliphatic dicarboxylic acid is recovered more effectively.

Title: Spinning pot
Inventor: YOSHIZUMI YUKIO
IPC: D01D7/02
Filed: 1979-07-19
Abstract: PURPOSE:The body of spinning pot is composed of a fibrous reinforcing material  and a thermosetting resin and the wall of the body is made thin so that the wall  thickness is adjusted in a specific range, thus reducing the weight of the pot without  adverse effect on the strength and saving the electric power consumed on revolution. CONSTITUTION:The body of spinning pot 1 is composed of a fibrous reinforcing material such as carbon fiber or aromatic polyamide fiber and a thermosetting resin such as epoxy, unsaturated polyester or phenolic resin and the side wall is made 1- 5mm. thick where the ratio of M/V is preferably adjusted to 0.15-0.45 when M and V represent the total weight in gram and capacity in cubic centimeter respectively. EFFECT:As the thin side wall results in contraction of the outside diameter of the pot, the windage loss on revolution is extremely reduced and the energy necessary for keeping the required revolution becomes low. Further, the resultant pot is excellent in durability and safety.

IPC: H03K5/08
Filed: 1981-06-12
Abstract: PURPOSE: To eliminate the effect of the temperature change and the noise, by setting the refernce voltage of one of the two TRs forming a differential amplifier at the reference level of the signal voltage of the other TR and turning on both TRs with saturation when the reference voltage is equal to the reference level.  
     CONSTITUTION: The emitters of TR1 and TR2 are connected in common, and the reference voltage is supplied to the base of the TR2 through the resistances 7 and 8 plus a resistance 9. The reference voltage is set substantially equal to the reference level of the signal voltage VIN which is supplied to the TR1. The resistances 3, 4, 5 and 6 are set so that both the TR1 and TR2 are turned on with saturatin when the reference voltage is equal to the reference level. Thus the collector voltages VC 1  and VC 2  are set at the same level although the base current of the TR1 and TR2 has a change by the ambient temperature, the external noise, etc.
